Product features Bayonet probe, 6mm, -50 to 400 ° C

Description and application

All of this resistance sensors are primarily designed to measure the temperature of solid substances, but can also be used to measure the temperature of liquids or gaseous substances. To mount the sensor on the measuring point, use a bayonet nut screwed on a spring. 

La combination of bayonet nut, spring and bayonet connector matching can provide a higher contact pressure from the sensor to the measuring point or compensate for possible changes in the distance between the nut and the measuring point during the measurement. 

The maximum temperature range of the sensors is between - 50 and 350°C (400°C short term). The range of individual design variations is narrowed down to the type of temperature sensing element and power cable. The sensors respect the level of protection IP50 to IP67 according to EN 60529, depending on the type of input cable.


GUILCOR thermometers with bayonet locking are fitted with one or more Pt100 sensors (other sensitive elements on request), which are installed in a protective stainless steel sleeve with anti-torsion spring. The bayonet cap, which can be adjusted with the spring, ensures high operational reliability in temperature measurement thanks to the locking cap of the bayonet cap with the screw nipple. 

In the case of mechanical vibrations or temperature-induced expansions, the defined contact pressure ensures good thermal coupling. In addition, it is possible to rotate the bayonet cap on the spring and thus adjust the depth of immersion of the sensor in a bore or the preload of the spring according to their own requirements.

Principle of construction / operation

The measuring resistor is installed in an insulated VA sleeve with a permanently connected connection line. The tension spring is mounted on the sleeve with the adjustable bayonet cap, which is used to set the desired polarization.
